Electric parameters of the magnetized plasma taking into account a small spatial charge are calculated. It is shown that the size of sensitivity of such plasma to a magnetic field is a constant, but smaller than the size of sensitivity of the plasma calculated for a case of weak magnetic fields and tends to zero in case of the strong magnetized plasma. The size and the sign of a space charge define also uniformity of plasma in a transverse section and with small pressure of gas and rather big size of mobility of the charged particles, plasma is always uniform in a category transverse section. With pressure boost in gas and with increase in parameters of movement of the charged particles, plasma becomes the nonuniform in a gas transverse section.

Investigation of feedback parameter dependence of autodyne system is performed upon the emission level from the radar target, when this level is commensurable with the level of own oscillations. At that, the autodyne model is used for frequency-stabilized case by additional high-Q cavity. This model allows an analysis of the autodyne system both in the case of usual single-circuit oscillating system and in the case of additional cavity presence. We state by numerical modeling that at strong reflected emission, the boundary value of the feedback parameter, at which autodyne characteristic smoothness is lost, is less than unity. Results obtained permit a calculation the dynamic range and the maximal range of autodyne action under conditions of the strong reflected emission.

Often apply spread spectrum signals to protection of communication systems against narrow-band hindrances. Protective abilities of a communication system at the same time are defined by the size of base of a spread spectrum signal. If hindrance power too big, isn't enough such protection. In this case additional ways of protection, for example, a rejection of a powerful hindrance are necessary. The present report is devoted to assessment of deterioration in autocorrelated function because of a rejection of a part of a range of a difficult signal together with a hindrance.

Fluctuations in electrochemical systems strongly depend on the electrochemical processes taking place therein; therefore study of fluctuation phenomena becomes important for diagnostics of such type of systems. In the framework of this paper, the experimental data obtained during the discharge of the Li-Ion battery (ICR 18650) with nominal voltage of 3,6 V and capacity 2,6 A.h are analyzed. The measurements were carried out in open-circuit conditions for different battery state-of-charge. Fluctuations in open-circuit conditions comprise new information that allows enhancing the diagnostic properties of electrical fluctuations. The corresponding properties can be used as a basis for efficient diagnostic systems of lithium batteries. The possibility of analysis in the in open-circuit conditions makes it possible to realize non-destructive testing of batteries without changing their actual technical state and include primary batteries into the scope of application.

The synthesis of waveguide band-pass elliptical filters is realized. The thin transverse resonance diaphragms with an aperture in the form of a rectangular window with two metal L-shaped ridges are used as resonators of the filter. The electrodynamic problem of calculating the complex conductivity of the diaphragm is solved. An equivalent circuit of the resonant diaphragm is proposed and the correspondence between the geometric dimensions of its aperture and the parameters of the circuit is determined. The synthesis results of an elliptic filter for a rectangular waveguide WR137 with passband of 7,5% and length of 34 mm are presented.

This paper is devoted to the study of the effect of a nonhomogeneous in space and time-varying magnetic induction on parametric generation in crossed fields. It is shown that the introduction into the interaction space of the instrument along with the variable magnetic induction and a constant magnetic field inhomogeneous along the axis of the device leads to an increase in the output characteristics: the induced current, the induced power, and as a consequence the increase in efficiency. In the final authors shows the main output characteristics of the considered case of parametric generation in crossed fields.

Medium-power (10-100 W) THz-band gyrotrons operating in a continuous-wave (CW) mode are of great importance for many applications such as spectroscopy, plasma diagnostics, non-destructive inspection, stand-off detection of radioactive materials, biomedical applications, etc. For all these applications, high frequency stability and tunability within 1-2 GHz frequency range is typically required. Apart from different existing techniques for frequency stabilization, phase locking has recently attracted strong interest. In this paper, we present the results of numerical simulation phase locking by injection of the external driving signal, self-injection locking by delayed reflection, and mutual phase locking of two coupled gyrotrons. Mode competition effect on phase locking is investigated.

Based on the results of simulation of resonant inverter of voltage the adjustment and output characteristics are constructed for synchronous and asynchronous methods of control. A comparative evaluation of energy efficiency was carried out for the resonant inverter of voltage with frequency, phase and time-pulse method of control. It is shown that when the output frequency is increased, using the method of synchronous time-pulse modulation with energy circulation provides more efficient operation of resonant inverter of voltage.

This article considers modeling of the gas-filled neutron tube's ion source with discharge initiated by the non-recombined plasma from the previous pulse. The simulation was carried out with a homogeneous distribution of the non-recombined plasma with a concentration of 5.108 cm−3. In the case of filling the neutron tube volume by atomic hydrogen with pressure of 10-3 Torr, the slew rate of the extracted atomic hydrogen ion current equals only 10 mkA/mks. For increasing this value gas mixture of atomic hydrogen and xenon at a pressure of 0.5.10−3 Torr or molecular hydrogen at a pressure of 10−3 Torr to the atomic hydrogen were utilized. This led to increasing of the slew rate of the extracted atomic hydrogen ion current to 100 mkA/mks with xenon and 20 mkA/mks with molecular hydrogen.
